Replacement frequency of septum and injection port liner is reduced,consequently prolongs GC running time greatly The Microseal is distinct from traditional septa in that the Microseal has two independent sealing mechanisms to perform these functions. O-rings seal the syringe needle during sample injection.
CS Septa Low temperature appliions PTFE coated silicone Good Good Excellent Good 200 °C TCS Septa Medium/high Due to the loion of septa in the sample path,much attention has been focused on today as the injection port or GC inlet.
GC Septa. GC septa from Specialty Silicone Products (SSP) are used in gas chromatography (GC),a group of techniques for separating and analyzing volatile compounds. In GC systems,a sample is injected through a rubber septum into a heated vaporization chAijiren. A carrier gas transports the sample into the GC column.

GC Inlet Septa is used to seal the injection port and it is an interface for injecting the sample. The septa are made of polydimethylsiloxane-a similar polymer is used for stationary phases. When heated,such siloxane polymers will form degradation products that will show up in the GC analysis.

NoteDue to differences in inlet design,the actual septum temperature for a given inlet setpoint can vary by manufacturer. Restek recommends using only BTO septa in Thermo TRACE and Focus GCs. *) For 17 mm inlets,the maximum temperature for BTO septa is 330°C. For all injectors,minimum recommended operating temperature for BTO septa is 250°C

Rated to 400°C,Advanced Green injector port septa was designed to coine significantly longer injection life,low bleed and low injection port adhesion. The result is a general use green septa made of uniquely formulated silicone rubber you can use for all your critical analyses.
enable large volume injection (LVI),headspace and on-line sample preparation to be performed. Plunger Design Most plungers are made from stainless steel with an option of a PTFE tip on the end. If no PTFE tip is present then the syringe is not classified as gas tight and should only be used for liquid sampling (i.e. not for headspace).

Our portfolio consists of GC vials and LC vials,GC caps and LC caps,and GC septa and LC septa. Through our biological line,we offer glass and plastic vials for optimal measurement of samples by
When samples need to be taken in a closed system,use of an injection port septum may be a good way to insert a needle to take a sample without having to shut the entire system down. Rubber septum design varies widely depending on the appliion.
Our portfolio consists of GC vials and LC vials,GC caps and LC caps,and GC septa and LC septa.
